6 DIFFERENT PROPERTY CLASSIFICATION OF MATERIALS

1 Mechanical Property2 Electrical Property3 Thermal Property4 Magnetic Property5 Optical Property6 Deteriorative Property

RMIT University©19/04/23

MECHANICAL PROPERTIES Relates to deformation to an applied load or force.

ELECTRICAL PROPERTIESElectrical conductivity and dielectric constant

THERMAL PROPERTIESHeat capacity and thermal conductivity

MAGNETIC PROPERTIESDemonstrate the response of a material to the application of a magnetic field
